The lungs take in Oxygen which is carried by the blood to the cells of our body in order for respiration to occur and we get energy. The transfer of Oxygen to the blood happens in the Alveoli. The Alveoli are little bumpy ball like things at the end of the bronchioles in our lungs. The Carbon Dioxide is taken out of our blood in the Alveoli too.
The main purpose of circulation is to supply oxygen rich blood to the body's tissues and organs. Circulation also removes waste from the organs.
Insulin's chief role in the body is to keep blood sugar within a fairly narrow "comfort" zone.

When people lay in the same position for a long time they will get what is called Bed Sores. These come from constant contact with the sheets which will rub on the skin and not let air get to the skin. Rotating the patients position helps to avoid this. It's also for circulation reasons. Blood needs to flow to all parts of the body. When you are in the same position blood has a difficult time going where there is pressure applied from laying still. Rolling over helps circulation also. Plus it gives the patient a different view.
The patient could have had a seizure. That would explain their eyes rolling back and the breathing stopped. Tubereculosis could explain vomiting blood if the blood came from the lungs. Those are also symptoms of shock.
